Quizplus · Accepted Answer

The clinic is using polysomnography, which is the monitoring of multiple physiological functions during sleep, including respiration, body temperature, muscle movements, and brain activity. Positive sleep state analysis (PSSA), somnambulism, and biofeedback are not techniques used in sleep studies.
